Description
This X-Function is added for GeoTIF image processing. It is used to generate pixel intensity distribution of a gray-scale image to a new worksheet. You can enter a series of pixel values separated in space to be ignored during the frequency count. Note that missing values will be ignored by default.
Algorithm
The computation uses function from OpenCV Main API. Please refer to the OpenCV Main API Help file, Version 2.4.11.0 and read imgproc. Image Processing topic.
